I second the use of Wx::SingleChoiceDialog or Wx::MultiChoiceDialog like jmlynesjr sugested.

Parsing XML like you do is not a good choice, use a dedicated module, something like this:

use strict;
use warnings;

use XML::Simple;
use Data::Printer;

my $data = do { local $/; <DATA> };          # slurp DATA

my $ref = XMLin(
    $data,
    #KeyAttr    => { Question => 'questionId' }, # unordered data
    ForceArray => ['item'],
    ContentKey => '-content'
);

p $ref;

Notice that a valid XML must have a root tag. I also changed a little the structure...
